The cellular effects of laser therapy includes the down-regulation of cells responsible for inflammation. The inflammatory process is controlled by a multitude of chemical mediators, and certain wavelengths of light can trigger immune cells to release them. This helps decrease inflammation by reducing swelling and promoting faster healing.

Once the target tissue is no longer inflamed, laser therapy accelerates cellular repair and tissue regeneration, allowing tissues to heal quicker and more effectively. Furthermore, laser therapy is thought to improve collagen organisation (the building blocks for healthy tissues) and the biomechanical properties of these tissues.

The application of laser therapy improves blood flow to treated areas and enhances nutrient and oxygen delivery due to increased vasodilation which results in improved tissue healing. Increasing circulation also contributes towards the analgesic effect laser therapy can have.

Arguably one of the most important effects of laser therapy is its ability to reduce pain. Laser therapy helps reduce pain and discomfort by stimulating the release of endorphins which aids a variety of musculoskeletal and neurological pain conditions, on both an acute and a chronic level. These endorphins activate natural pain relief mechanisms within the body and inhibit nerve fibres associated with pain.

Laser therapy is a non-surgical and typically pain-free treatment option that does not require anaesthesia or sedation. Unlike some other electrotherapy, laser therapy does not involve the application of a conductive gel, and the fur in the area does not need to be clipped.
